I own a PS Audio P600, and a PS Audio PPP as well. And a Furman REF20i for just the amp (and alternatly the video stuff)
So i can relate.
Two possibilities: first, if a wire is loose in the light switch, it will magnify the transient pulse a great deal. You should check the switch connections, and the receptical connections in the wall receptical for tightness. Copper deforms easily, and with a new house, they also may have been in a hurry. So turn off the power and check and tighten those connections at/in the walls.
A loose wire at a screw really does magnify the switch change greatly.
And remember the PS Audio reduces bad stuff by about ninty percent so some bad stuff still gets through the PS Audio designs.
A second possiblility: (though less likely)
Perhaps your light is not sending a pulse through the wiring, rather through the air? You may have some interconnect, or internal wiring of a component which is particulary susceptible to a radiated pulse.
Audio Research Phono boxes are very susceptible to outside noise entering, and i am certain other stereo items are also. Then any non insulated non coax interconnects like Kimber may be the source. EMF is a strange thing.
I would check the wiring thing first.
If it is a freestanding lamp, add a ferrite to the cord. ordinary 1" long 1/2 thick tubes work, i squeeze the folded wire through the hole and flip it over the other end so it is caught in it's own loop on all my non stereo cords, like for lamps... even the refrigerator.
You might also just replace the switch that is making the pop. Nearly any construction bits are the cheapest possible. Replacing it with a part from Menards or Home depot may make it quieter electrically.
If it is a small 12 volt light, the transformer inside it may be causing the transient, and sticking the ferrite on that cord might help. The lamp transformer may just not be very good and cause a back emf wave to travel into the powerline. but it too may have a loose wire at it's wall receptical.
